Kelvin Keith Chapman (born June 2, 1956) is a retired Major League Baseball player.

The team featured several other future New York Mets players, including Mookie Wilson, Neil Allen and Jeff Reardon.

He replaced strong fielding but light hitting Doug Flynn, who was the Mets regular second baseman in 1978.

Chapman's major league debut occurred on April 5, 1979 against the Chicago Cubs at Wrigley Field.

Chapman played for the Mets AAA-league team, the Tidewater Tides of the International League for most of the 1979 season.

After Chapman got off to a strong start with Tidewater in 1984,[1] he was recalled to the Mets in May, more than 4 years after his previous Major League game in 1979.

With a batting average of just .174,[2] Chapman was sent back to the Tidewater Tides after playing his last Major League game on July 24, 1985.

[2] The Mets did make an offer to remain in the organization, as perhaps a manager in their farm system, but Chapman, who had injured his knee during the 1985 season, opted to retire and return home to California.
